Criar location para payload Pix

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations provide only basic hints (non-readOnly, non-destructive, non-idempotent, openWorld). Description adds that the location is 'reutilizável' (reusable), which is a behavioral trait. However, it does not discuss side effects, permissions, or behavior on multiple calls. Given limited annotations, description is adequate but not rich.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with purpose, no unnecessary words. Every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter and an output schema (hinted), the description covers main purpose and usage guidance. It could mention that the output includes a location ID, but this is likely in the output schema. Minor gap: no mention of prerequisites or idempotency, but overall complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% for the single parameter (body with tipoCob). The tool description does not add any additional meaning about the parameter beyond what the schema provides. Baseline of 3 is appropriate since schema covers parameters, though schema descriptions are minimal.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states it creates a reusable location for associating a charge with a dynamic payload, and distinguishes itself by noting it should be used before generating QR code when separate management is needed. This verb+resource combination differentiates from siblings like pix_generate_qr_code or pix_create_charge.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Description provides explicit context: use before generating QR code when you need to manage the association separately. It does not explicitly state when not to use or name alternatives, but the guidance is clear enough for an AI agent to decide when to invoke this tool over others.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
